Subbi TD04l on a RB20de+T

ok here´s the deal
I get scammed on my RB25 Highflow turbo and know iam in need of a cheap replacement.
The first thing which comes in my mind was a crappy Ford escort RS t3...but from a 1,6 engine how could make that thing any power on a 2 liter?

second idea...a subaru TD04.
Theyre dirt cheap and come from a 2liter ,,sport,, engine LOL, atleast makes over 200hp with those crappy long headers and the awesomo intakemani

i know on hondas they provide instant boost but thats no suprise with that headflow...which a RB20 will never get

so
opinions on a TD04 an a 2liter straight six?

bevor i forget
a huge benefit of the td04 is that i can upgrade to anything between TD05,Td07 and so on and dont always have to change the manifold and downpipe cause theyre made for crappy subbi flanges

I reallywouldnt worry about inadiquate head flow on a straight six. Vs a subies set of heads. Im sure if a subaru with long *** unequal length headers can spool that turbo your rb can do just fine. When i chose mine i just picked a turbo from abcar with similar displacement. ( well sort of) mine is a stock 2.4 liter wuere as the car my turbo came from was a 2.0 to 2.2 liter engine that was a bit more built.. worked out great...so i wouldnt stress it.
